Is there a difference in operations when power on and when the SD card is inserted for the first time?

[HMasu.1]

I use STM32MP151CAA3 Cortex-M4 on my custom board.

I have created Linux image running on my custom board.

In the case that the SD card is inserted for the first time, Linux image is running successfully.

However, in the case that I turn power off and power on with the SD card inserted, boot fails despite using the same SD card.

Is there a difference when power on and when the SD card is inserted for the first time, such as the files to read?

What should I investigate to solve this problem?

Hi @HMasu.1​ ,

Could you please share boot logs in case of success and failure.

@ArmandG​  will look at it.

Hi @Community member​ 

Thank you for your reply.

I will share boot logs.

-​Log_Boot_Error.txt: boot logs in case of failure

-​Log_Boot_Success.txt: boot logs in case of success

-​Log_Reboot_Error.txt: logs when I execute reboot command (reboot failed)

Best Regards,
